A system consisting of air, considered as an ideal gas, initially at 400 K and 1 bar experiences the two different types of interactions described below. In each case, the system is brought, at constant volume, from initial state where the temperature is 550 K.

a. The temperature rise is brought about adiabatically by stirring the air with a paddle wheel. Deteremine in kJ/kg.K:

-The amount of entropy produced

-The change in exergy

-The exergy destruction.

for exergy calculations, let To=20 deg C, and po=1 bar.
